Abstract
Description
Technical Field
[0001] This utility model belongs to the field of straight seam welded pipe manufacturing technology, and specifically relates to an automatic tracking and scraping device for external burrs of high-frequency welded pipes. Background Technology
[0002] High-frequency welded pipe is a type of metal pipe produced by forming hot-rolled coils using a forming machine and then utilizing the skin effect and proximity effect of high-frequency current. Its characteristics include high welding speed and a small heat-affected zone, making it suitable for the production of thin-walled pipes. However, after forming, high-frequency welded pipes often have a large number of burrs at the weld joints on the outer wall, which require cleaning, affecting subsequent production and use. Furthermore, due to the large size and weight of high-frequency welded pipes, existing automatic burr tracking and scraping devices still need improvement in terms of scraping effect, stability, and service life. In addition, different devices also have limitations in adapting to different specifications of high-frequency welded pipes and handling burrs of different materials and thicknesses.

[0035] The high-frequency welded pipe external burr automatic tracking and scraping device described in this utility model:
[0036] Before work begins, the auger installed on the base plate 1 drives the coarse scraper and fine scraper on the top plate 3 to a suitable position for the scraper (the specific position should be 50 mm below the scraper from the outer surface of the steel pipe). The base plate 1 and the top plate 3 are then locked with the fixing plate 14 to fix the position of the top plate.
[0037] The scraper of the coarse scraping device is adjusted to a suitable working position by using the lifting and moving power mechanisms. The parameters of the fine scraping device are set, and the machine is started for trial operation. During the trial operation, the position of the coarse scraping device and the parameters of the fine scraping device are adjusted according to the specific working conditions to ensure normal operation of the machine in accordance with the process requirements.
[0038] The base plate 1 is made by CNC cutting and welding of thick steel plate. The top and bottom surfaces of the base plate are made to ensure parallelism. The bottom edge of the side plate is welded to the base plate. During welding, attention should be paid to the stability of the fit dimensions and the welding deformation should be controlled.

[0042] The horizontal servo motor and the horizontal lead screw, and the vertical servo motor and the vertical lead screw are connected by a plum blossom flexible coupling.
[0043] Because the weld seam on the high-frequency welded pipe is set parallel to the axis of the high-frequency welded pipe, after the high-frequency welded pipe is welded, it moves horizontally under the action of the external equipment. During the movement, it passes under the scraper of the coarse scraping mechanism and the fine scraping mechanism in sequence. At the same time, the weld seam of the high-frequency welded pipe cooperates with the scraper to remove the external burrs at the weld seam. Under the action of the water-cooled laser probe, the fine scraping mechanism will not stop working due to the high temperature of the outer surface of the steel pipe.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
